Since we will be removing the winlinks as we process them, it is
important to use RB_FOREACH_SAFE (now that it is available) to make
sure that the traversal is not affected by removing the current
winlink.
---
Example:
Without the "safe" traversal, some winlinks may not be removed:
tmux -L test-kw-a new-session -ds kw-a # window 0
tmux -L test-kw-a new-window -dt kw-a # window 1
tmux -L test-kw-a new-window -dt kw-a # window 2
tmux -L test-kw-a kill-window -at kw-a # kill all but 0 (i.e. 1 and 2)
tmux -L test-kw-a list-windows -t kw-a # oops, window 2 is still left
tmux -L test-kw-a kill-session -t kw-a
Note: The above kill-window command will crash the server unless the
previous "use session from -t" patch has also been applied.
Also note: It may be difficult to paste the above commands unless
something like my "client: defer reading stdin" patch is
applied. A normal shell script should work fine.
Another example: a session with windows 0, 1 (active), 2, 3:
"kill-window -a" kills just 0, and 2 (should also kill 3)
